Evaporative cooling systems and Legionnaires' Disease
One of the questions we frequently get asked is whether you can catch Legionnaires’ disease from evaporative coolers . We are happy to report that there have been no recorded cases of a portable evaporative cooler causing Legionnaires’ disease and research indicates transmission of the bacteria is not possible by the evaporative method. What is Legionnaires’ disease? It is a very serious type of pneumonia caused by breathing in small droplets of water that contain bacteria called Legionella. Legionella bacteria are found naturally in moist environments such as lakes and rivers, and other water sources. The bacteria causing Legionnaires disease are very common, but only build up to dangerous concentrations in - · Warm, stagnant water - evaporative cooling fans operate from a supply of cold fresh water, so the bacterium doesn’t have the opportunity to multiply. · Limescale and slime – regular cleaning of wet surfaces with a mild bleach solution, will p
